Quick answer: Mimio is a transparent, fully disclosed fasting-mimetic formula with one real randomized trial behind it. That trial was small (42 adults), lasted eight weeks, was funded by Mimio Health and studied overweight adults averaging 62 years old. It measured appetite and blood lipid markers, and it found no difference from placebo on cognition or quality of life. At $100 a pouch, Mimio costs $3.33 a day. If what you want from Mimio is spermidine or NAD+ support, our pick is a single-ingredient product: Eternal Elixir Spermidine 10mg costs $0.83 per serving.
Eternal Elixir makes spermidine, NMN and NR supplements that compete with Mimio; they are our pick for readers who want single ingredients, and every figure for Mimio below comes from Mimio’s own product page and its published trial. For this Mimio review we read the label, the price and the study directly rather than repeating the brand’s summary. Where we state a claim, we also state how much evidence sits behind it.
Mimio review: what you get for $100
Mimio Biomimetic Cell Care comes as a pouch of 60 capsules. The label serving is two capsules a day, so one pouch lasts 30 days. A one-time purchase is $100. The subscription is $90 a month, which Mimio describes as a 10% discount with free shipping, and it can be paused or canceled.
Mimio calls the product a “fasting mimetic.” Its product page says each ingredient is naturally raised in the body during a 36-hour fast, and that the formula aims to create fasting-like effects without skipping meals. That is a claim about recreating a metabolic state, which is a bigger promise than most longevity supplements make.
Two things work in Mimio’s favor. The formula is fully disclosed, with milligram amounts for every ingredient instead of a proprietary blend. And the company links to its own published studies rather than pointing vaguely at “research.” Those are the reasons this product deserves a close read.
What you do not get is flexibility. One pouch gives you four compounds at fixed ratios. If you already take an NAD+ precursor or spermidine, part of every Mimio serving overlaps with what you have.
What is in a Mimio serving
Mimio’s product page lists four actives per two-capsule serving. We read the panel in September 2026.
| Compound | Per 2-capsule serving | Why it is in the formula | Evidence level for that use |
|---|---|---|---|
| Palmitoylethanolamide (PEA), ultra-micronized | 600 mg | Mood, comfort and recovery signaling | Moderate: several human trials, mostly outside longevity |
| Oleoylethanolamide (OEA) | 400 mg | Hunger and satiety signaling | Limited: small human trials |
| Nicotinamide | 250 mg | NAD+ precursor | Well studied as a vitamin B3 form, but not the form used in most recent NAD+ trials |
| Spermidine | 8 mg | Autophagy and cell renewal | Limited in humans: strong cell and animal work, thinner human outcome data |
By weight, the two largest doses are PEA and OEA, the appetite and comfort compounds. So by mass, Mimio is mostly a satiety formula with an NAD+ precursor and spermidine added.
The 8 mg of spermidine is a real amount, not a label sprinkle. Our review of the spermidine evidence covers where that research is solid and where it is still early.
The clinical evidence behind Mimio
Mimio says it has three published clinical studies. The public record is more specific than that headline.
The main trial. Grant and colleagues published a randomized, double-blind, placebo-controlled trial in Scientific Reports in February 2026 (full text on PubMed Central). 42 participants were evaluated, 23 on Mimio and 19 on placebo, for eight weeks. They were overweight adults aged 62 on average, with an HbA1c around 6.0.
- 91% of the Mimio group improved their mealtime appetite ratings, versus 47% on placebo (p = 0.003).
- Total cholesterol, LDL cholesterol, LDL particle number, oxidized LDL, non-HDL cholesterol and fasting glucose fell more in the Mimio group than on placebo.
- The Mimio group reported less abdominal pain and bloating.
- Quality of life, eating-behavior scores and cognitive scores did not differ from placebo.
- Adverse effects did not differ between the groups.
Who ran it. The paper states that the study was funded by Mimio Health LLC, and that the corresponding author is from Mimio. The authors disclose this openly, which is the right way to handle it. It is still a reason to count the result as promising rather than settled.
Evidence level: one company-funded randomized trial. It supports appetite and blood-lipid effects in older overweight adults over eight weeks. It does not support the cognition positioning, because the cognitive scores did not separate from placebo. It says nothing about lifespan in people.
The other studies. A second study, published in Nutrition Research in December 2024, was a small dose-finding trial in healthy young men that looked at absorption and short-term markers (DOI 10.1016/j.nutres.2024.10.006). It shows the compounds are absorbed. It does not show that a 62-year-old will feel a difference. A medRxiv preprint from April 2025 has the same lead author and design as the Scientific Reports paper, so it reads as an earlier version of the same trial rather than an independent third study.
Mimio’s own product page also marks several of its mechanism claims with an asterisk that says the data comes from in vitro or animal research. Read those as laboratory findings, not human results.
Dose gaps between trials and retail labels are common in this category. Our supplement dose gap report compares trial doses against what US labels deliver.
Nicotinamide is not NMN or NR
Mimio’s NAD+ ingredient is 250 mg of nicotinamide. Nicotinamide, NMN and nicotinamide riboside (NR) all feed NAD+ production, but they enter by different routes, and most recent human NAD+ trials used NMN or NR rather than nicotinamide.
That is a scope note more than a criticism. Mimio is a fasting-mimetic formula that happens to include an NAD+ precursor. It is not an NAD+ product. If NAD+ support is your main goal, compare the precursors directly. Our guide to NAD+ supplements sets out how the three forms differ, our comparison of NMN supplements covers the NMN options, and our article on NMN safety in human trials summarizes what the studies report.
Eternal Elixir sells both of the other routes. NMN 500mg capsules come 90 to a bottle at 500mg per capsule. Nicotinamide Riboside 500mg comes as 60 capsules, one capsule per serving.
What Mimio costs per day
This is the number most readers come for. Each product below is priced at its own label serving, read from the live product pages in September 2026.
| Product | Label serving | Price per pack (USD) | Cost per serving |
|---|---|---|---|
| Eternal Elixir Spermidine 10mg (our pick) | 1 capsule, 60 servings per bottle | $49.99 | $0.83 |
| Eternal Elixir Nicotinamide Riboside 500mg | 1 capsule, 60 servings per bottle | $59.99 | $1.00 |
| Mimio Biomimetic Cell Care, subscription | 2 capsules, 30 servings per pouch | $90.00 | $3.00 |
| Mimio Biomimetic Cell Care, one-time | 2 capsules, 30 servings per pouch | $100.00 | $3.33 |
These are not equivalent products. A Mimio serving carries four actives, while each of ours carries one. The table shows what each approach costs per day, not which one does more. The point is that $3.33 a day, or $3.00 on subscription, is the number to keep in mind when you compare Mimio with building your own routine.
Our comparison of spermidine supplements covers the wider market if spermidine is the part of Mimio you care about most.
Four questions to ask before you buy a fasting-mimetic supplement
- Which ingredient do you actually want? If the answer is spermidine or an NAD+ precursor, a single-ingredient product costs less per serving and lets you choose the dose.
- Do you match the trial population? Mimio’s trial enrolled overweight adults with an average age of 62. Results in that group may not carry over to younger, leaner adults.
- What did the trial measure? Appetite, blood lipids and fasting glucose improved. Cognition and quality of life did not change compared with placebo.
- Can you commit to eight weeks? The trial ran for eight weeks, and Mimio recommends at least that long, so budget for two pouches before you judge it.
Mimio review verdict: who it suits and who should skip it
Mimio stands out in a category full of relabeled commodity powders. The dosing is transparent, the four compounds are plausible, and there is a real randomized trial with a real placebo arm. Mimio is also direct in its own materials that eight weeks is the minimum trial period.
It suits you if appetite control and blood-lipid markers are your actual goals, you are closer to the trial population than to a healthy 25-year-old, and you would rather pay $3.33 a day for one product than assemble a routine yourself.
Skip it if your goal is NAD+ support specifically, if you already take spermidine or an NAD+ precursor and would be paying twice, or if you want to control each dose yourself. In that case our pick is single ingredients: spermidine at $0.83 per serving, NR at $1.00 per serving, or NMN at 500mg per capsule.
Readers comparing other multi-ingredient longevity formulas may also want our NOVOS Labs review and our Do Not Age review, both of which cover products in a similar price range. For single-brand NR, see our Tru Niagen review.
The overall read: Mimio is a well-made, well-documented product carrying a promise that runs ahead of its evidence. Buy it for what the trial measured, not for the 36-hour-fast headline.
Mimio review FAQ: common questions
Does Mimio actually work?
For the outcomes that were measured, the trial result is positive with caveats. In an eight-week randomized trial of 42 overweight adults averaging 62 years old, Mimio improved appetite ratings and blood-lipid and fasting glucose markers compared with placebo. The same trial found no difference in cognition, quality of life or eating-behavior scores, and it was funded by the manufacturer.
How long does it take for Mimio to work?
Mimio recommends at least eight weeks, and the trial outcomes were measured at the end of an eight-week period. One pouch lasts 30 days, so a fair trial means at least two pouches, or $200 at the one-time price.
What are the active ingredients in the Mimio supplement?
Each two-capsule serving contains 250 mg of nicotinamide, 600 mg of ultra-micronized palmitoylethanolamide (PEA), 400 mg of oleoylethanolamide (OEA) and 8 mg of spermidine, according to Mimio’s product page.
What are the benefits of taking Mimio?
Mimio’s own randomized trial supports reduced hunger and better mealtime appetite, improved cholesterol and fasting glucose markers, and less bloating over eight weeks in older overweight adults. It did not show an effect on cognition, and no human study has measured an effect on lifespan.
What are the side effects of taking Mimio?
In the published trial, adverse effects did not differ between the Mimio and placebo groups. That comes from 23 people taking Mimio for eight weeks, so it is not a large safety dataset. If you take prescription medication, are pregnant or are breastfeeding, talk to your doctor before starting any new supplement.
What is the best alternative to Mimio?
Our pick is Eternal Elixir Spermidine 10mg for readers who want the spermidine part of Mimio on its own, at $0.83 per serving instead of $3.33 a day. For NAD+ support, Eternal Elixir Nicotinamide Riboside 500mg costs $1.00 per serving. If you want four compounds in one product and accept the price, Mimio remains the simpler single purchase.
Is Mimio better than a spermidine or NAD+ supplement?
They are different tools. Mimio delivers 8 mg of spermidine with three other compounds at a fixed ratio for $3.33 a day. A single-ingredient product lets you set the dose yourself and costs less per serving. If you want one product covering four pathways, Mimio makes sense. If you want control and a routine you can adjust, single ingredients are the better route, and our guide to longevity supplement stacks shows how people combine them.
